This document relates generally to the motor vehicle field and, more particularly, to closures and closure systems for vehicle closure panels such as liftgates.
BACKGROUNDVehicles, particularly those including rear cargo areas, are often provided with vertically articulable closure panels for the cargo areas, for ease of access thereto. An example would be a rear liftgate for a sport-utility vehicle, van, or mini-van.
Such closure panels articulate vertically, i.e. are hingedly attached to the vehicle and swing upwardly when opened. A disadvantage to this configuration is that, when the panel is at a fully opened position, the handle used to close the panel is at a highest position and may be difficult to reach by persons of shorter stature.
To address these and other problems, the present disclosure describes an adjustable-length handle assembly for a vertically articulating closure panel which allows lengthening or shortening the handle length as desired to accommodate a user's stature.
SUMMARYIn accordance with the purposes and benefits described herein, in one aspect an adjustable-length handle assembly for a vertically articulating closure panel for a vehicle is provided, comprising a retractor, a flexible web disposed to deploy from and retract into the retractor, and a gripping portion disposed at a distal end of the flexible web. The assembly may further include a flexible web guide roller and a brake for the flexible web. In embodiments, the retractor and/or the flexible web guide roller are carried by the vertically articulating closure panel.
In embodiments, the retractor comprises a reel including a biasing member disposed to retract the flexible web. The biasing member may be selected from a torsion spring, a flat coil spring, or a constant force spring. The vertically articulating closure panel may be a liftgate.
In other aspects, closures comprising the described extendable handle assembly and vehicles including such closures are described.
In the following description, there are shown and described several preferred embodiments of the disclosed adjustable-length handle. As it should be realized, the devices are capable of other, different embodiments and their several details are capable of modification in various, obvious aspects all without departing from the descriptions set forth herein and described in the following claims. Accordingly, the drawings and descriptions should be regarded as illustrative in nature and not as restrictive.
The accompanying drawing figures incorporated herein and forming a part of the specification, illustrate several aspects of the disclosed adjustable-length handle and together with the description serve to explain certain principles thereof. In the drawing figures:
Reference will now be made in detail to the present preferred embodiments of the described adjustable-length handle, examples of which are illustrated in the accompanying drawing figures.
DETAILED DESCRIPTIONAs summarized above, it is desirable to provide an adjustable length handle for a vehicle closure such as a liftgate, to accommodate users of differing heights. To solve this and other problems, at a high level the present disclosure describes an adjustable-length and extendable/retractable handle for a vehicle. It is contemplated to use the described handle in association with a vertically articulating closure panel, for example rear closure panels such as liftgates. However, other uses are possible and contemplated.
With reference to
With reference to
In more detail, with reference to
To cause deployment/retraction of the flexible web 170/gripping portion 190 from a desired portion of the vertically articulating closure panel 120, a flexible web guide roller 180 is provided through which the flexible web is guided, which acts as a hinge point for the band. The flexible web guide roller 180 may be provided with a brake mechanism 230 for selectively preventing motion of the flexible web 170 once the flexible web has been extended or retracted to provide a desired gripping portion 190 height.
In alternative embodiments (not shown), it is known to provide a detent mechanism associated with the reel 200 for preventing any deployment or retraction of the flexible web 170, and a release mechanism to release the detent. The skilled artisan is very familiar with such mechanisms.
The flexible web 170 may be fabricated of any suitable material, for example a webbing or strapping as is known in the seat belt arts, a plastic or polymer, a metal-reinforced plastic or polymer, or others.
As will be appreciated, by the described assembly a convenient, simple and effective adjustable-length handle is provided for a vertically articulating closure panel for a vehicle, for example a rear liftgate. By the described mechanism, a user may easily adjust a length at which the handle hangs relative to the ground when the closure panel is fully opened. Thus, users of practically any stature can be accommodated.
The foregoing has been presented for purposes of illustration and description. It is not intended to be exhaustive or to limit the embodiments to the precise form disclosed. Obvious modifications and variations are possible in light of the above teachings. All such modifications and variations are within the scope of the appended claims when interpreted in accordance with the breadth to which they are fairly, legally and equitably entitled.
